Sorted it, for anyone else who's having trouble: if you've imported the cameras got into configuration mode, the adv gps click the tools button then select copy to favorites. This can take a while to add em all. You should now have the icons on screen. Also untick add cameras as they are detected.

Just a quick question on this subject:

Loads of the cameras dont have speeds assigned to them, so if I go through one and how do I assign it a speed on the fly? do I just add another camera with the correct speed? Any suggestions would be great.
